Increase Protein intake and decrease Fat intake

*17,544 women without a history of infertility for 8 years as they tried to become pregnant or became pregnant.
*A dietary score based on factors previously related to lower ovulatory disorder infertility (higher consumption of monounsaturated rather than trans fats, vegetable rather than animal protein sources, low glycemic carbohydrates, high fat dairy, multivitamins, and iron from plants and supplements) and other lifestyle information was prospectively related to the incidence of infertility.
*A combination of five or more low-risk lifestyle factors, including diet, weight control, and physical activity was associated with a 69% lower risk of ovulatory disorder  infertility and an estimated population attributable risk of 66% (95% confidence interval 29-86%).
